<p>A fin cooler (10) having a plurality of hollow cooling fins (14), each provided with a coolant liquid flow passage and further having a header block (12) provided with separate coolant liquid inflow and outflow channels (30, 34), is placed in a closed loop coolant liquid circulation network. By regulating fluid flow, fin temperature can be manipulated to improve process control and product uniformity. The cooling fins (14) operate at a temperature high enough to prevent glass volatiles form condensing on the fin surfaces and to prevent the formation of fin corroding acids. The closed loop cooling path prevents fin coolant passage occlusion or clogging.</p> |
